Patent GB-558797-A (GB)
Title: Improvements in or relating to means or appliances for controlling the paying-out of ropes
IPC: B66C13/02
Filed: 1942-06-02
Abstract: 558,797. Cable brakes. PARK, R. T. M. June 2, 1942, Nos. 7446 and 8207. [Class 78 (ii)] Means for checking and stopping the paying- out of ropes &c. and supporting the load comprises a spring-pressed brake block bearing on the rope and forcing it against removable abutments so as to slow down or stop the movement of the rope by friction. The rope 7 passes under two bolts 3, 4 and over two abutment rods 5 between two wooden side cheeks 1. The bolts 3, 4 carry rotatable sleeves to:reduce the rope friction, and the rods 5 from the limbs of a removable U-member insertable through co-incident holes in the cheeks 1 and retained in place by the legs of a U-member 6. Chains 6a prevent loss of the U-member 5, 6. The wooden brake-block 12 is screwed to the underside of a lever 11 hinged at 10 and pressed down by a hooded spring 14. When it is desired to allow the load, which may be a lifeboat suspended by the rope 7 from davits, to lower, the pressure of the spring 11 is counteracted by a tongue 18 extending under the lip of the lever 11 from a shaft 17. A handle 24 and a footlever 22 control the shaft 17 to effect lifting of the lever 11. In case the suspended load may be greater than the spring 14 can control, a tongue 19 extending over the lip of the lever 11 is also provided on the shaft 17, thus enabling pressure on the lever 24 to force the block 12 still harder against the rope 7. When the load is to be raised, the U-member 5 is withdrawn, thus permitting full removal of the device from the rope. For re-insertion hooks 25a are employed to lift the rope 7 above the level of the abutments 5, which are then inserted and secured. A two-fold device may be provided for controlling two ropes, and the control may act on both ropes or an independent handle and foot-lever may be fitted for each rope. The lever 11 may be fixed at one end and itself form the spring, in addition to, or in place of, the spring 14.

Title: Improvements in and relating to automatic control systems
Inventor: GOULD RAYMOND WALTER FRANK
IPC: G05D16/20
Filed: 1955-03-16
Abstract: 830,398. Automatic control systems. NATIONAL RESEARCH DEVELOPMENT CORPORATION. June 18, 1956 [March 16, 1955], No. 7682/55. Class 38 (4). In a system in which variation of a condition from a desired datum causes a variation or variations in the electrical properties of one or more elements of an A.C. bridge, the variations being insufficient to balance the bridge under operating conditions, the error signal which is arranged to restore the condition to its desired value comprises a voltage consisting of the difference between the rectified bridge voltage output and a first reference voltage somewhat lower than corresponds to the datum condition when the rectified signal voltage is less than said first reference voltage, and consisting of the difference between the voltage of the rectified signal and a second reference voltage somewhat higher than corresponds to the datum condition when the rectified signal is higher than the second reference voltage. An armature 12 is moved in response to a change of pressure by a bellows to change the values of the inductance of coils 13, 14 in an A.C. bridge which is normally i.e. at the desired pressure, unbalanced, to change the degree of unbalance. The error signal which is amplified, doubled, and filtered in units 17, 18, 19 is passed to a pair of doubletriode relay circuits 25, 26 through a cathode follower 21, and an error rate signal derived from a differentiating network 23 is passed through a neon lamp 24 and mixed therewith. The relays which are arranged one to operate when the mixed error and error rate signals is less than a threshold voltage, and one when the mixed signal is greater than a threshold voltage, operate a reversible control motor 28 to reduce the error. The circuit provides also a dummy error source 32 for setting up, manual control of the motor, error, and error rate signal meters, and warning lights operated by the relays. In an alternative relay arrangement, Fig. 2 (not shown), wherein the double triodes have a common cathode resistor, the error rate signal is applied with the threshold voltage to the grid of one triode and the error signal is applied to the other, the electromagnetic relay being in one or the other anode circuits according to whether it is required to operate above or below the threshold voltage. The A.C. bridge is fed by a Wien oscillator and the system is stated to be applicable to the control of any other variable such as temperature or velocity.

Title: Control of two slewing and luffing cranes working together to transport one and the same load
IPC: B66C13/30
Filed: 1969-02-12
Abstract: 1,210,041. Electric control of cranes. SIEMENS A.G Feb. 12, 1969 [Feb. 12, 1968], No. 7696/69. Heading G1N. A load-transporting arrangement comprises two slewing and luffing cranes K 1 , K 2 , and a control system so that the cranes may both be controlled from a single station to work together to transport one and the same load from a position P to one P<SP>1</SP>. Fig. 1 is a plan view with A 1 , A 2 , being respective working radii i.e. the horizontal projections of jib lengths, α 1 , α 2 , being respective slew angles and # 1 , # 2 , being respective luffing angles i.e. # is the angle between a respective crane jib and its horizontal pivot axis. It is shown that to effect a required movement of the load, two criteria must be satisfied; (i) the luffing angle, #, must be varied in dependence upon its associated slewing angle, α, so that the product cos α. cos # remains constant over the entire travel of the load; (ii) the length PP<SP>1</SP> for the crane, K 1 , must equal that for the crane, k 2 , i.e. 2a, tan α, = 2a 2  tan α 2 . Figs 3 and 4 (not shown) are schematic diagrams of control arrangements. That of Fig. 3 controls the luffing speed of an associated crane in accordance with the first criterion, there being one such arrangement on each crane. That of Fig. 4 is provided on a driverless crane to follow-up the other, manually-controlled crane, to control its slewing-speed so as to satisfy the second criterion. If the initial slewing angles and the initial working radii of the two cranes are identical, as illustrated in Fig. 5 (not shown), the control arrangement for slewing, Fig.4, may be omitted.

Title: Improvements relating to the manufacture of closed, hollow bodies from plastic materials
IPC: B28B11/16
Filed: 1936-03-14
Abstract: 455,580. Moulding hollow bricks &c. by extrusion. AKT.-GES. FUR INDUSTRIEGASVERWERTUNG, 91, Gradestrasse, Britz, Berlin. March 14, 1936, No. 7761. Convention date, March 14, 1935. [Class 87 (ii)] A machine such as is described in Specification 424,117 for cutting a hollow extruded string 3 of plastic material, provided with plugs at intervals, so as to produce closed hollow bodies such as bricks, comprises a cutter 8 mounted on a shaft 7 which is oscillated by a crank mechanism 32, 33, 35 to effect the cut, the shaft being moved axially by a spring 36 during cutting and being returned to initial position after the cutting operation by a screw 4 on a power shaft 1. The string 3 drives frictionally a drum 50 provided with a cam 28 which rocks a spring-influenced member 27 about a fixed pivot 26. The motion of the member 27 transfers, by means of a rod 25, a frame 22 so that blocks 23, 24 carried thereby are engaged either with a cam 15, or with a cam 16 set at 180‹ on a shaft 13. The frame 22 is linked at 21, 19, 18 to a guide 17 so that movement of the frame by the cams effects axial movement of the shaft 13 thereby controlling the engagement and disengagement of a member 12 fast on the shaft, with a clutch member 10 positively driven by a pinion 9 on the power shaft 1. The rotation of the shaft 13 swings the cutter shaft 7 and also, through linkage 51, 52 operates the mouthpiece of the extrusion press (not shown), to produce solid zones in the otherwise hollow extruded string. In order to produce hollow bricks having a middle transverse partition, the cutter shaft is oscillated only at alternate actuations of the crank 35, this result being achieved by mounting the crank 35 loose on the shaft 7 and coupling it with a driving arm 41, Fig. 3, by a sliding bolt 45 having a head 48 which is engaged by an abutment 49 to disconnect the coupling during the first return of the cutter-shaft, the next actuation of the crank 35 serving only to release the head 48 from the abutment 49. The movement of the cutter-shaft is employed to actuate a ratchet wheel 38 geared to delivery rollers 40 for removing the severed bricks.
